I know one can host a Jekyl based static site/blog via Github pages. Can one do the same with a static site/blog based on AngularJS?
You can but you can't use html5 mode (removes the # from urls). If you use html5 mode, you have to redirect all requests to the root url since its a single page app. Since you can't use server side code on GitHub pages, you can't do this. So, if you don't mind the # in the url, go for it. If you want to use html5 mode, you need to look for hosting elsewhere.
From the Angular docs...
"Using [html5] mode requires URL rewriting on server side, basically you have to
rewrite all your links to entry point of your application (e.g. index.html)"
EDIT:
You can make use of some clever hacks to make this work if you really want to. The hacks are outlined in detail here. In summary, you rename your index.html to 404.html and github will serve it at all routes
I would say yes considering all the angular UI github pages are in fact angular apps with demos:
http://angular-ui.github.io/
http://angular-ui.github.io/bootstrap/
etc
There is one conflict between Jekyll and Angular to be aware of.
Liquid, which is included in Jekyll also uses {{ }} for evaluating expressions. To change the expressions that angular interprets (so it doesn't conflict with Liquid) use:
var myapp;
myApp = angular.module('myApp', []);
myApp.config([
'$interpolateProvider', function($interpolateProvider) {
return $interpolateProvider.startSymbol('{(').endSymbol(')}');
}
]);

Yes, you can. I recently played around with AngularJS/Typescript and github pages and was able to deploy the site.
Since AngularJS is just javascript, you can actually use any decent webserver, e.g. github pages.
Here is the demo.
You can find source code here. This repository contains typescript source code which you have to compile in order to get the appropriate javascript file. Then you basically put this include this file into your index.html and you are done.

The Scenario
I'm developing the front-end (CSS only) of an Angular SPA.
I'm not especially familiar with Angular routing.
I'd like to add a standalone page containing Bootstrap components just for development purposes (yes, I know this means it won't be a single page application anymore). This way I have one unified view with all the components so I don't have to switch back and forth while working on the CSS. It also acts as documentation for the Bootstrap for the other devs to refer to.
What I've tried
I originally added a bootstrap.html page to the app folder, alongside the app's index.html This worked at first, but has now stopped working. What would be the best/standard way to achieve something like this?
Update: I've managed to fix some of the JS errors, so the page is up and running again. My question remains though: "is there a way of adding a standalone page that is considered standard/best practise, or is it literally just add a separate HTML page at the app root?"
If you use a target='_self' in your linking anchor tag, this should force a full page reload, and that will avoid the angular routing - which is where I expect your request is getting hijacked (by design).

Answering your updated question
Not to my knowledge, since (as you correctly pointed out) this mixes the SPA design pattern.
I am working on a project where I am using Angularjs (1.x) as web framework. In that app, I needed routing, so I am using angular-ui-router. I configured the routes in my app and its working fine, but exclamation(!) in routes is not clear to me and why these exclamation comes to routes.
Also, I saw demo example code provided by angular ui router . In Hello World tutorial, I observed that routes are with hash(#) but not with exclamation(!) eg: https://some_url/#/home
but in Hello Solar System tutorial routes are with hash(#) and exclamation(!) eg. https://some_url/#!/hello.
Config for angular ui router in both tutorials are in same way. Thats why I am not able to understand what exactly is making the difference in both of them. So, I need help to understand this.
Any useful suggestion will be appreciated.
Thanks!
To let everyone know the answer for this question, adding what I understood from comments.
This change can be observed in angular version > 1.6.x. In previous version it was like just # (hash bang) only.
To get url like # way only, you can simply write in this way,
appModule.config(['$locationProvider', function($locationProvider) {
$locationProvider.hashPrefix('');
}]);
This change was introduced in version 1.6.0, which you can see https://github.com/angular/angular.js/blob/master/CHANGELOG.md#location-due-to.
Also, adding here what is written there:
The hash-prefix for $location hash-bang URLs has changed from the empty string "" to the bang "!". If your application does not use HTML5 mode or is being run on browsers that do not support HTML5 mode, and you have not specified your own hash-prefix then client side URLs will now contain a "!" prefix. For example, rather than mydomain.com/#/a/b/c will become mydomain.com/#!/a/b/c.
How can I tell whether a (Drupal 7) web app was built using Angular by looking at the page source, and not having to ask the developers?
The best way to check is to write "angular" on browser console. If you get any object [With child objects as "bind","bootstrap","callbacks","module" etc.] then its an angular web app.
You can install a chrome or firefox extension called Wappalyzer. It tells you which site you are navigated on in your browser and the stack they use.
Find it here: https://www.wappalyzer.com
You could try: angular.version.full first. If this doesn't work, try getAllAngularRootElements()[0].attributes["ng-version"]. The reason being in Angular 1 the former will work and from angular 2 onwards the later will work.
If it's an online site you can use http://builtwith.com/ and it usually can give you a good and useful bunch of information about that site.
However if they are using angular you can take a look at their page sources to see if they are using any attributes of angular like ng-repeat for example
You can also take a look at the sources that your browser get while browsing that site to see if javascript files for angularjs are included among the sources.
Application declared using ng-app directive
very simple controller and directive
check for ng-model, ng-repeater attributes in the code. All these attibutes are written in small letters.
Also you can check by typing in the console(ctrl + shift + i) and navigate to console tab. There type in window.angular.version --> it displays the version of the site your are currently inspecting.
Try
https://builtwith.com/
This is the website that currently gives you the most detailed information about what technologies a site uses. They will let you do 5 free lookups a day.
https://wappalyzer.com/
is a good one too, and serve as a complement to builtwith. I don't think there is a limit of lookups, but the results are less detailed.
Those two used together may give you more insight.
use window.getAllAngularRootElements() in the browser console if it return some value its an angular application
For Angular, in Chrome's inspector, in the Elements tab, inside the body element is an element called app-root containing ng-version, which shows the Angular version it's using.
There is a Google Chrome extension called 'ng-detector'. It may be obtained from the Google webstore:
https://chrome.google.com/webstore/detail/ng-detector/fedicaemhcfcmelihceehhaodggfeffm
It creates a small icon next to the URL bar that indicates whether or not it thinks the page was created using Angular, although I have not thoroughly tested its validity.
Install chrome extension React-Detector, it works!
window.getAllAngularRootElements() worked for me
You can install a Chrome or Firefox extension called Augury. It tells you if app is an angular or not.
I'm deciding whether it's safe to develop my client-facing app in AngularJS using pushState.
I've read that when using pushState in an AngularJS app, we don't need to worry about Googlebot because it can now execute enough JS to produce an HTML snippet for itself. But then I wonder about Bing, Facebook and other bots and scrapers. The tutorials I've seen for making AngularJS SEO-friendly all deal with apps that use hashbangs (#!). These don't apply to me since I'm not using hashbangs.
Does anyone have insight into this problem? What are some methods for ensuring an AngularJS app that uses pushState is SEO-friendly and Social-scraper-friendly? If you use a service like Seo4Ajax or prerender.io I'd appreciate your thoughts on it.
Note: As I understand it, when developing single page apps in the last couple of years it has been necessary to send HTML snippets to SEO crawlers. This was accomplished by using hashbangs and a meta tag that let Google, Bing and Facebook know that it needed to replace the bang (!) with an _escaped_string when making a request. On the server you'd listed for requests with _escaped_string and deliver the appropriate HTML snippet using a tool to generate HTML snippets like phantomJS.
Now that we have pushState, I don't see how we indicate to javascript-less bots what part of the URL to rewrite with an _escaped_string or even if it's necessary. I'm having trouble finding any information beyond "you're site will be okay with google ;)".
Here are some other SO questions that are similar but have gone unanswered.
Angularjs vs SEO vs pushState
.htaccess for SEO bots crawling single page applications without hashbangs
Here's a solution I posted in that question and am considering for myself in case I want to send HTML snippets to bots. This would be a solution for a Symfony2 backend:
Use prerender or another service to generate static snippets of all your pages. Store them somewhere accessible by your router.
In your Symfony2 routing file, create a route that matches your SPA. I have a test SPA running at localhost.com/ng-test/, so my route would look like this:
# Adding a trailing / to this route breaks it. Not sure why.
# This is also not formatting correctly in StackOverflow. This is yaml.
NgTestReroute:
----path: /ng-test/{one}/{two}/{three}/{four}
----defaults:
--------_controller: DriverSideSiteBundle:NgTest:ngTestReroute
--------'one': null
--------'two': null
--------'three': null
--------'four': null
----methods: [GET]
In your Symfony2 controller, check user-agent to see if it's googlebot or bingbot. You should be able to do this with the code below, and then use this list to target the bots you're interested in (http://www.searchenginedictionary.com/spider-names.shtml)...
if(strstr(strtolower($_SERVER['HTTP_USER_AGENT']), "googlebot"))
{
// what to do
}
If your controller finds a match to a bot, send it the HTML snippet. Otherwise, as in the case with my AngularJS app, just send the user to the index page and Angular will correctly do the rest.
Supposedly, Bing also supports pushState. For Facebook, make sure your website takes advantage of Open Graph META tags.
I'm working on a big project. This project already has complicated structure. Most pages are generated on server-side with Twig.
Now we move the project to AngularJS.
It is not possible to use angular-way routing on whole project just now. But somewhere, it is necessary.
And here comes our trouble.
If I add 'ng-app' in html tag, for example, on some pages angular add hash in url.
And what is strange for me, that it's not everywhere.
On start page (project/profile9868766), url is clear as it is. But on some other (project/community/list), angular does something like that: project/community/list/#list .
And it is extremely undesirable.
There are no any angular routes, configured in $route service yet.
Please, help me to find out what causes that behavior, and what should i do to make all the things to go right way.
I want to add ng-app in html tag and not get any troubles with existing code, that may use hashes. And I want to use angular directives, controllers and other stuff, including $location service to set and track hashes on some pages. And later move everything to Angular and only after that start using Angular routes.
Thanks!
PS: English is not my native language, sorry about some weird constructions and mistakes. ))
Make sure to turn on html5mode
http://docs.angularjs.org/guide/dev_guide.services.$location
But the hash is inevitable on non-html5 browser.
The latest version of angular (v1.0.7) seems to have fixed this issue.
